I've had these burners for over a year now and they're my number one choice for days out and overnight camping.

They're called Speedster Burners and they're from a UK maker called Speedster Backpacking Products: https://speedsterstoves.co.uk/alcohol...

I've no affiliation or anything with them, I just really like their burners and there doesn't seem to be much awareness of them in the outdoor community. Well worth a look.

As best as I can tell, they do post internationally too.
